GeForce GTX 480		250 Watts
	Difference: 130 Watts (108%)

Memory Bandwidth

In theory, the Radeon RX 470 4GB should be 19% quicker than the GeForce GTX 480 in general, because of its greater bandwidth. (explain)

Radeon RX 470 4GB		211200 MB/sec
GeForce GTX 480		177408 MB/sec
	Difference: 33792 (19%)

Texel Rate

The Radeon RX 470 4GB should be quite a bit (more or less 182%) faster with regards to texture filtering than the GeForce GTX 480. (explain)

Radeon RX 470 4GB		118528 Mtexels/sec
GeForce GTX 480		42000 Mtexels/sec
	Difference: 76528 (182%)

Pixel Rate

The GeForce GTX 480 will be a little bit (approximately 13%) faster with regards to anti-aliasing than the Radeon RX 470 4GB, and also capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 480		33600 Mpixels/sec
Radeon RX 470 4GB		29632 Mpixels/sec
	Difference: 3968 (13%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (measured in MB per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
